Within the clinical environment, the technology is often referred to as laser Doppler flowmetry; when images are made, it is referred to as laser Doppler imaging. Laser Doppler flowmetry (LDF) measures cerebral blood flow (CBF) at a single point on the cortical surface using a confocal laser and detector pair. This method can easily be incorporated into the experimental setup to provide information on CBF, a hemodynamic variable not directly assessable by optical imaging. The purpose of the study is using a laser Doppler imaging device (Easy-LDI) as an additional tool to assess perfusion. In this method, the changes in the frequency of the laser ligth provide information regarding perfusion of the monitored tissue. Laser Doppler imaging (LDI) can be used to measure superficial blood flow in the skin and other vascularized tissues. A laser Doppler perfusion imager functions by projecting a visible-to- infrared laser beam onto the surface of a tissue.

Laser Doppler imaging of skin microcirculation 115 LDI measurement was defined by the absence of a numerical output, i.e. the signals derived from a measuring site had been automatically excluded during processing. In the present study the stepper motors were set to move two steps at a time, and the lower cut-off frequency Selected Chapters in Medical Technology A project on: Aimago SA and Laser doppler imaging Vu Thanh-Hieu Nguyen Alex Dixon Trygve Utstumo The sections in this article are Development and Use of Laser Doppler Flowmetry Laser Doppler Imaging Endothelial Dysfunction LDI and Iontophoresis Studies Using LDI in RA Patients Conclusion Keywords: laser Doppler imaging; laser Doppler flowmetry; endothelial dysfunction; iontophoresis; rheumatoid arthritis Laser Doppler Imaging of Skin.

2016, 24:349-355. Laser Doppler imaging (LDI) is often compared to laser speckle imaging and whilst there are some similarities, both techniques offer unique advantages. LDI generally offers deeper penetration enabling enhanced visualisation of small vessels below the tissue surface, perfect for angiogenesis modelling or through skull pre clinical cerebral blood flow imaging.

Laser Doppler imaging can enable mapping of the local arterial resistivity index, and the possibility to perform unambiguous identification of retinal arteries and veins on the basis of their systole-diastole variations, and reveal ocular hemodynamics in human eyes.
